On Aug. 19, workers will begin removing the existing ground-mounted UTMB signs at the John Sealy Hospital entry at Eighth and Market streets and the employee drop-off area near Ninth and Market streets. New signs will be installed in these areas as well as at Sixth and Market streets. During the construction, alternate traffic lane closures will be occurring; however, one lane will always remain open. The hospital entrance will not be blocked at any time. The work should be completed within four to six weeks, weather permitting.
